Setting the time interval for Pilot Assist *
Pilot Assist can be set with different time inter- vals.
Different time intervals to the vehicle in front can be selectedand shown in the driver displayas 1-5 horizontal lines - themore lines the longer the timeinterval. One line representsabout 1 second to the vehicle
in front, 5 lines represents about 3 seconds.
NOTE
When the symbol in the driver display shows a car and a steering wheel, Pilot Assist fol-lows a vehicle in front at a preset time gap. When only one steering wheel is shown, there is no vehicle within a reasonable distanceahead.
Control for time interval.
Decrease time interval
Increase time interval
Distance indicator
–Press the steering wheel button (1) or (2) to increase or decrease the time interval.
> The distance indicator (3) shows the cur- rent time interval.
In order to follow the vehicle ahead in a smooth and comfortable way, Pilot Assist allows the timeinterval to vary noticeably in certain conditions.For example, at low speed, when the distancesbecome short, Pilot Assist increases the timeinterval slightly. Note that a short time interval only allows the driver a short time to react and take action if anyunforeseen problem should arise.
NOTE
Only use the time intervals permitted by local traffic regulations. If Pilot Assist does not appear to react when activated, this may be because the time dis-tance to the vehicle in front is preventing anincrease in speed. The higher the speed the longer the calcula- ted distance in metres for a given time inter-val.

Automatic standby mode
Pilot Assist is dependent on other systems, e.g. stability control/anti-skid ESC. If any of theseother systems stops working, Pilot Assist isswitched off automatically. In the event of automatic deactivation a signal will sound and a message is shown in the driver dis-play. The driver must then intervene and adaptthe speed and distance to the vehicle ahead. Automatic deactivation may occur if:
• the speed is below 5 km/h (3 mph) and Pilot Assist is uncertain whether the vehicle aheadis a stationary vehicle or an object, such as aspeed bump.
• the speed is below 5 km/h (3 mph) and thevehicle ahead turns off so that Pilot Assist nolonger has a vehicle to follow.
• speed is reduced to below 30 km/h(20 mph) - only applies to cars with manualgearbox.
• the driver's hands are not on the steeringwheel
• the driver opens the door
• the driver takes off the seatbelt
• engine speed is too low/high
• wheels lose traction
• brake temperature is high
• the parking brake is applied •
the camera and radar unit is covered by e.g.snow or heavy rainfall (camera lens/radiowaves are blocked).
Reactivating Pilot Assist from the
standby mode
NOTE: The illustration is schematic - details may vary depending on car model.
–Press the steering wheel button (1).
> The speed is then set to the most recently stored speed.
NOTE
A marked speed increase may occur once the speed has been resumed by pressing steer- ing wheel button

IMPORTANT
In certain situations, Pilot Assist steering assistance may have difficulty helping thedriver in the right way or it may be automati-cally deactivated - in which case, the use ofPilot Assist is not recommended. Examples ofsuch situations may be that: •the lane markings are worn, missing or cross each other.
• lane division is unclear, for example, whenthe lanes divide or merge or at exits or inthe event of multiple sets of markings.
• edges or other lines than lane markingsare present on or near the road, e.g.curbs, joints or repairs to the road sur-face, edges of barriers, roadside edges orstrong shadows.
• the lane is narrow or winding.
• the lane contains ridges or holes.
• weather conditions are poor, e.g. rain,snow or fog or slush or impaired viewwith poor light conditions, back-lighting,wet road surface etc.
The driver should also note that Pilot Assisthas the following limitations: • High kerbs, roadside barriers, temporary obstacles (traffic cones, safety barriers,etc.) are not detected. Alternatively, theymay be detected incorrectly as lane
markings, with a subsequent risk of con- tact between the car and such obstacles.The driver must ensure him/herself thatthe car is at a suitable distance from suchobstacles.
• The camera and radar sensor does nothave the capacity to detect all oncomingobjects and obstacles in traffic environ-ments, e.g. potholes, stationary obstaclesor objects which completely or partiallyblock the route.
• Pilot Assist does not "see" pedestrians,animals, etc.
• The recommended steering input is forcelimited, which means that it cannotalways help the driver to steer and keepthe car within the lane.
The driver always has the possibility of correcting or adjusting a steering intervention imposed byPilot Assist and can turn the steering wheel tothe desired position.
Steep roads and/or heavy loadBear in mind that Pilot Assist is primarilyintended for use when driving on level road surfa-ces. The function may have difficulty in keepingthe correct distance from the vehicle ahead whendriving on steep downhill slopes - in which case,be extra attentive and ready to brake. Do not usePilot Assist with a heavy load or with a trailer con-nected to the car.
Miscellaneous
•Off Road drive mode cannot be selected
when Pilot Assist is activated.
NOTE
The function uses the car's camera unit, which has some general limitations, see the"Limitations for camera unit" section.
NOTE
The function uses the car's radar unit, which has some general limitations, see the "Limita-tions for radar unit" section.

City Safety
City Safety uses visual, haptic and acoustic sig- nals to alert the driver of any pedestrians,cyclists, large animals and vehicles that appear.The car then brakes automatically unless thedriver him/herself acts within a reasonable time.
Location of the radar unit 14
.
City Safety can prevent a collision or reduce colli- sion speed. City Safety is an aid to assist a driver who is at risk of colliding with a pedestrian, large animal,cyclist or a vehicle. The City Safety function can help the driver to avoid a collision when driving in queues, e.g.when changes in the traffic ahead, combined witha lapse in attention, could lead to an incident. The function helps the driver by automaticallybraking the car in the event of an imminent riskof collision if the driver does not react in time bybraking and/or swerving. City Safety activates a short, sharp braking proce- dure, normally stopping the car just behind thevehicle in front. For most drivers this is well out-side normal driving style and may be perceived asuncomfortable. City Safety is activated in situations where the driver should have started braking earlier, whichis why it cannot help the driver in every situation. City Safety is designed to be activated as late as possible in order to avoid unnecessary interven-tion. The driver or passengers are not normally aware of City Safety - it only intervenes in a situationwhere a collision is immediately imminent. City Safety can avoid a collision with a vehicle ahead or a bicycle by reducing the speed of thecar by up to 50 km/h (30 mph). For a pedestrian,City Safety can reduce speed by up to 45 km/h(28 mph). If the speed difference is greater than 50 km/h (30 mph) or 45 km/h (28 mph) respectively, CitySafety's automatic braking cannot prevent a colli-sion but it can mitigate the consequences of acollision.In the event of a risk of a collision with a largeanimal, City Safety can reduce the car's speed byup to 15 km/h (9 mph). The braking function forlarge animals is primarily intended to reduce thecollision force at high speeds. Braking is mosteffective at speeds above 70 km/h (43 mph) andless effective at low speeds.

Rear Collision Warning
The Rear Collision Warning (RCW) function can help the driver to avoid being hit by a vehicleapproaching from behind.
RCW is activated automatically each time the engine is started. The RCW can warn the driver in a vehicle approaching from behind that a collision is immi-nent by rapidly flashing the direction indicators. If, at a vehicle speed below 30 km/h (20 mph), the RCW function detects that the car is in dan-ger of being hit from behind, the seatbelt ten-sioners may tension the front seatbelts and theWhiplash Protection System safety system isactivated. Immediately before the collision, RCW may also activate the foot brake in order to reduce the for-ward acceleration of the car during the collision.However, the foot brake is only activated if thecar is stationary. The foot brake releases immedi-ately if the accelerator pedal is depressed.
LimitationsIn certain cases the RCW may have difficultyhelping the driver in the event of a collision risk.This can be for example:
• if the vehicle approaching from the rear isdetected too late
• if the vehicle approaching from the rearchanges lane at the last moment •
if the vehicle approaching from the rear has aspeed exceeding 80 km/h (50 mph).
NOTE
In certain markets, RCW does
not give a
warning with the direction indicators due to local traffic regulations - in such cases, thispart of the function is deactivated.
NOTE
The warning with direction indicators for Rear Collision Warning is deactivated if the warn-ing distance for collision warning in the CitySafety function is set at the lowest level "
Late".
The seat belt pre-tensioning and braking functions are, however, still active.

Blind Spot Information
*
The Blind Spot Information (BLIS) function is designed to give a warning of vehicles diago-nally behind and to the side of your car so as togive assistance in heavy traffic on roads withseveral lanes in the same direction.
BLIS is a driver aid intended to give a warning of: • vehicles in the car's blind spot
• quickly approaching vehicles in the left and right lanes closest to the car.

Indicator lamp
The BLIS button in the centre display's func- tion view activates/deactivates the function.
Principle of Blind Spot Information
Zone in blind spot
Zone for quickly approaching vehicle.
The BLIS function is active at speeds above 10 km/h (6 mph). The system is designed to react when: • your car is overtaken by other vehicles
• another vehicle is quickly approaching your car.
When BLIS detects a vehicle in Zone 1 or aquickly approaching vehicle in Zone 2, the indica-tor lamp on the door mirror on the affected sideilluminates with a constant glow. If the driver acti-vates the direction indicator on the same side asthe warning, the indicator lamp will change over from a constant glow to flashing with a moreintense light.
NOTE
The lamp illuminates on the side of the car where the system has detected the vehicle. Ifthe car is overtaken on both sides at thesame time then both lamps illuminate.
WARNING
Blind Spot Information does not work on sharp bends. Blind Spot Information does not work when the car is reversing.
WARNING
Blind Spot Information is a supplementary aid and does not work in all situations. Blind Spot Information is no substitute for a safe driving style and the use of rearview anddoor mirrors. Blind Spot Information can never replace responsibility and attention by the driver. It isalways the driver
